    摘要： An electrolyte for non-aqueous electrolyte battery containing at least one compound selected from the group consisting of lithium difluoro(bis(oxalato))phosphate, lithium tetrafluoro(oxalato)phosphate and lithium difluoro(oxalato)borate as a first compound and at least one siloxane compound represented by the general formula (1) or the general formula (2) as a second compound in the electrolyte is disclosed. In addition to the improvement of initial characteristic, this electrolyte shows a tendency that storage stability, low temperature characteristic, etc. are superior, and exhibits well-balanced, superior, performances as a whole battery.

    摘要： An electrolytic solution for a nonaqueous electrolyte battery according to the present invention includes: (I) at least one kind of silane compound represented by the following general formula (1); (II) at least one kind selected from the group consisting of a cyclic sulfonic acid compound and a cyclic sulfuric ester compound; (III) a nonaqueous organic solvent; and (IV) a solute. The nonaqueous electrolyte battery with this electrolytic solution achieves a good balance between improvement of high-temperature storage characteristics under high-temperature conditions of 70° C. or higher and reduction of gas generation during high-temperature storage. Si(R1)x(R2)4-x  (1) In the general formula (1), R1 is each independently a carbon-carbon unsaturated bond-containing group; R2 is each independently selected from a fluorine group and a C1-C10 linear or C3-C10 branched alkyl group which may have a fluorine atom and/or an oxygen atom; and x is an integer of 2 to 4.

    摘要： To provide a manufacturing method with which lithium difluorophosphate powder can be recovered from a lithium difluorophosphate solution. A method for manufacturing lithium difluorophosphate powder is used which includes the steps of precipitating solid lithium difluorophosphate by adding a poor solvent to a solution in which lithium difluorophosphate is dissolved in a main solvent, and obtaining lithium difluorophosphate powder by solid-liquid separation of the solid lithium difluorophosphate from the liquid containing the main solvent and the poor solvent, wherein the relational expression between the octanol/water partition coefficient PP of the main solvent and the octanol/water partition coefficient PA of the poor solvent is defined by the following formula (1).
